Suction Caissons in Intermediate Soils

9th International SUT Offshore Site Investigation Geotechnics Conference Proceedings “Innovative Geotechnologies for Energy Transition”, 2023
Suction caisson supported jackets have been used on several recent offshore wind farm projects in Europe including Aberdeen Bay, Borkum Riffgrund 2 and Seagreen. Suction caissons are particularly sensitive to soil conditions, including 'intermediate' soils such as partially drained sands, silts, and heavily interbedded sands and clays.

Soil suction monitoring for landslides and slopes

Quarterly Journal of Engineering Geology and Hydrogeology, 2011
Rainfall is the most frequent triggering factor for landslides and the development of early warning systems has to take account of this. It is suggested that direct measurement of pore pressure gives the most reliable prediction of failure of a slope.

Influence of Soil Suction on Trench Stability

2007
A research project on the stability of temporary trenches in unsaturated soil is carried out in Belgium. The main objective of the project is to evaluate the seasonal variations of suction in the soil and to quantify the consequences of these suction variations on trench stability.

Measurement of Suction Stress and Soil Deformation at High Suction Range

Geotechnical Testing Journal, 2020
Abstract Suction stress is the effective stress independent of mechanical boundary conditions but is due to water content variation. It occurs on or near particle contacts and does not directly transfer through the soil skeleton and hence can only be and has been measured indirectly and deduced from soil’s strength or deformation.

Soil Suction‐Potential Model

Journal of Geotechnical Engineering, 1992
A suction‐potential model based on the diffusion equation is proposed whereby the suction is predicted at all times and depths in terms of a parameter K and the initial values of suction β0 The model shows that the suction ratio decays exponentially with time.

Effects of soil suction on dilatancy of an unsaturated soil

2005
There has been a growing interest in studying and modelling unsaturated soil behaviour over the last 15 years. It is generally believed that soil suction affects dilatancy of unsaturated soils and some suction-dependant dilatancy relationships are assumed in many flow rules of existing elasto-plastic models. However, limited laboratory data reported in

Measurement of soil suction using soil's resistivity

2009
During several years, the analyses of geotechnical problems have been dominated by solutions developed in the classical soil mechanics where the soil is considered completely saturated or dry, conditions that make the analyses less complicated. However, in many geotechnical problems, the engineer has to deal with unsaturated soils which properties are ...

Hydromechanical behaviour of expansive soils with different suctions and suction histories

Canadian Geotechnical Journal, 2016
This paper presents a number of experimental results of suction-controlled triaxial tests on a compacted weakly expansive soil with different suctions and suction histories. In terms of suction control methods, the high suction level (from 3.29 to 38 MPa) was realized by the vapor equilibrium technique and the low suction level (from 0 to 800 kPa) was

Temperature Effects on Soil Suction for Compacted Clay Soils

Advanced Materials Research, 2013
An investigation was conducted to determine the effects of temperature, compaction water content, and compaction efforts on soil suction of two expansive subgrade soils. For this purpose, two expansive soils were statically compacted at target water contents ranging from 5% to 20%.
